IMPROVEMENT IN COMBINED HARROWS AND ROLLERS.

Specification forming part of Letters Patent N 0. 177,636, dated May 23, 1876 application filed November 11, 1875.

harrow, and serving to weight the same, or'

as a roller, the barrow being folded over and serving to weight the roller; or the roller may, if desired, be unshipped, leaving the harrow free.

1n the accompanying drawing, Figure l is a perspective view of my implement in its extended form. Fig.- 2 is a section, at line 1 l,

of my implement in its folded condition, and in position for harrowing. Fig. 3 is a top view of the folded implement in position for rolling. Fig. 4'is a section at the line 2 2. Fig. 5 is an enlarged longitudinal section of a portion of one of-the rollers. e

A is a triangular frame of iron. B are the barrow -teeth of cimeter form, and having each around neck or shank, I), which occupies a corresponding orifice in the frame A, and is riveted above the same, so as to keep the tooth from separatingfrom the frame, and yet to allow it to rotate about its neck as an axis, so as always, and automatically, to present its sharp convex edge to the ground. The frame A of the harrow terminates rearward in eyes I O, which receive a rod, D, by which the floating frame E of the rollers F F is hinged to the barrow-frame. Projecting from the-rollerframe E is a screw-bolt, G, adapted in the folded condition of the implement to occupy an orifice, a, in the barrow-frame, and to be secured thereto by means of a thumb-nut, H.

By this means the weight of the rollers and roller-frame becomes available for the barrow,

'01: that of the barrow for the rollers, according to which side of the implement is uppermost. (See Figs. 2, 3, and 4.)

The rollers are hollowiron cylinders f, closed by heads f, which may be of wood or iron, and which are perforated for a plug, f, whose temporary removal enables the introduction of sand, or other heavy body or substance, when desired, to add to the weight of the roller.

Owing to the peculiar conformation and attachmentof the teeth my harrow is adapted placed to go easily over rocks, roots, or other impediments without injury to the implement or gearing, or strain upon the team.

I claim as new and of my invention- The combined barrow and roller, hinged one to the other in the manner described, to adapt them to fold compactly back to back,

in combination with the screw and nut for rigidly securing them together, as specified.

Intestimony of which invention I hereunto set may hand.
